Windows 10 preview build 14257 available in the Fast ring:

Preparing to begin a new development cycle, possibly bringing a lot of new features, Microsoft has pushed out a fresh Windows preview build to the Windows Insider members on the Fast ring. It’s just been a few days since the last preview build was released with a focus on fixing game-crashing issues and another preview build is already here. The current one seems to be setting up the basics before new features are released.

Teams are still early in their new feature work and changes in this build are mostly about laying the foundation for those features to start coming into builds.

Microsoft’s Gabe Aul had said a few weeks back that we will be seeing new features after a few builds. While we await the release of some feature-packed preview build hitting the Insider program, you can now get the Windows 10 14257 if you are on the Fast ring of the Windows Insider program. Take note of the known issues before you proceed, as there seem to be some serious troubles, especially the “Reset this PC” problem for which there is no workaround apart from reinstalling the Windows itself.

Windows 10 preview 14257 bug fixes:

The issue of periodic app crashes or other memory related app errors due to a memory management change has been resolved. If you were having issues launching the Git client for Windows, you should now be able to launch it in this build.

The Connect button now shows up again in Action Center.

F12 Developer Tools will now load correctly Microsoft Edge.

We fixed an issue where suggested apps were being shown on the Start menu even though “Occasionally show suggestions in Start” was turned off under Settings > Personalization > Start.

We fixed an issue where if you try to change the Lock screen picture with “Get fun facts, tips, tricks and more on your lock screen” turned on it will revert back to the default.

We fixed an issue where the positions of desktop icons get jumbled up after switching DPI settings from 100% to 150% or 175%.

We also fixed an issue where pasting files into a new .zip file (compressed folder) in File Explorer by either right-clicking or Control-V would not work. You should be able to paste tiles into new .zip files just fine now

Windows 10 preview 14257 known issues:

If you choose “Reset This PC” under Settings > Update & Security > Recovery – your PC will be in an unusable state. There is no workaround if your PC gets into this state and you will need to reinstall Windows. This issue will be fixed in the next build. You can still rollback to the previous build if for some reason this build doesn’t work out for you. This bug also existed in Build 14251 so please avoid resetting your PC on these builds.

You might see a WSClient.dll error dialog after logging in. We’re working on a fix for this but as a workaround, you can run the following in Command Prompt with administrative rights: schtasks /delete /TN “\Microsoft\Windows\WS\WSRefreshBannedAppsListTask” /F. This issue will be fixed in the next build.

The front-facing camera is unusable on PCs with Intel RealSense resulting in being unable to use Windows Hello or any other apps that utilize the front-facing camera.

After logging in to your PC, you may hit a UI issue in which Airplane Mode will incorrectly show as “on” even though your PC’s Wi-Fi is powered on. This is due to a timing issue between how the UI communicates and waits for the underlying platform to respond. The UI for Airplane Mode essentially does not wait long enough for the device’s physical radios to power on before reporting the current state. You can toggle the Airplane Mode on and off to get Airplane Mode back to showing the correct state.
